A friend of mine uses one on his j/109 after an expensive experience with his sail-drive. He clips the zinc "fish" to his backstay which I presume is grounded to the engine block.
His boat was never at a dock, and he has not had a problem since (3+ years) but I understand that there are so many factors involved in electrolysis that we don't know if it was the fish working or some other change - perhaps on other boats nearby in the mooring field (fore and aft moorings so other boats are close!) -- Jonathan Indigo C&C 35III SOUTHPORT CT > On Sep 25, 2017, at 14:08, Alan Liles via CnC-List <cnc-list@cnc-list.com> > wrote: > > Where do you connect overboard zincs?
